Nutritional Biochemistry

I often get asked, ‘Which diet works best?’. In my view, this is simply the wrong question. Nutritional biochemistry is a powerful lever in our longevity toolkit, but it is much more than fad diets or the number on the bathroom scale. A better question might be, “how can I use nutrition to support my metabolic health?”

Reframing the goal toward metabolic health is a critical starting point. From there, you can combine general principles of nutrition science (such as how much protein you need) with personalization tactics (such as using a CGM to monitor glucose levels) to build a nutrition plan that makes sense for you.

See the collection of audio clips, podcasts, and articles below to learn more about my nutrition and fasting framework.

Alternate Day Fasting

I’m left bewildered: there are more questions than answers in most scientific pursuits, but I want to stress the point here that these aren’t rhetorical questions.

#69 – Ronesh Sinha, M.D.: Insights into the manifestation of metabolic disease in a patient population predisposed to metabolic syndrome, and what it teaches us more broadly

“The way we raise our kids early on might actually set a pattern for how much of an accelerated life, or how much of a stressed out nervous system they might have later on. . . a lot of the behavioral patterns that we’re instilling in our kids are kind of setting the foundation for insulin resistance and inflammation early on.” —Ronesh Sinha

Can you maintain muscle during fasting?

But in the short-term (at least up to a week for most people), I believe you can maintain muscle mass while fasting, particularly if you’re resistance training.

Can you preserve lean body mass during “semi-starvation?”

All of this is very interesting, but what I find much more interesting in this study is that the placebo group did not lose any substantive LBM, while losing about the same amount of fat (10 lb) as the testosterone group, despite the severe CR/energy-deficit.
